OnePlus announced the 5T last week with Android Nougat 7.1.1, but one year-old OnePlus 3 and OnePlus 3T are already getting the new Android 8.0 Oreo. The manufacturer announced on its forums that OxygenOS 5.0 is being pushed to a small number of users, with a broader roll-out to come in the following days. Along with Android Oreo, the upgrade adds Parallel Apps and Picture-in-Picture features to the OnePlus phones. There is also Auto-fill and Smart text selection. OxygenOS retains its clean, minimalistic look, but gains new design for the Quick Settings panel. Along with the new features, there is also a security patch in the update. Android Oreo's Notification dots make it to the OnePlus 3 and OnePlus 3T users. The launcher also brings new app folder design. Source
